LOCOMOTIVE JOURNAL-BOX.

Specification of Letters Patent.

Patented Oct. 31, 1916.

T all whom it may concern:

Be it known that I, FREDERICK G. Cosno,

a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Locomotive Journal-Boxes, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to industrial locomotives and especially to journal boxes adapted for use on locomotives, the side frames of which are formed ofsteel sheets or plates.

It was formerly customary to construct the main side frames of small mine and industrial locomotives of special castings. hen the frames were so formed the castings were properly shaped to receive and hold thejournal boxes. At a later day the practice grew up of forming the frame side members of standard rolled steel sections such as channels or 'I-beams. For connecting these structural steel frames with the journal boxes special cast frames or pedestals were provided, and in connection with these there were means for longitudinally moving the boxes to accurately adjust the distance between the two axles. This adjustment was necessary because of the difliculty in accurately locating the cast frames or pedestalson the structural steel frame.

Recent locomotives have been provided with side'frames formed of a single sheet or plate of rolled steel properly reinforced by one or more angle bars or other structural sections. Openings are cut in the steel plates for the journal boxes and the object of my present invention is to provide journal boxes which can be mounted in these openings without the use of the heavy and expensive cast frames or pedestals which have been heretofore necessary in'connection with the structural steel locomotive frames before referred to.

Another object is to provide improved means for taking the wear resulting from the longitudinal thrust of the trackwheels and the axles against-the journal boxes.

Of the drawing which illustrates the form of my invention which I now deem preferable,F1gure 1 is a side elevation of a locomotive having ournal boxes embodying my invention. Fig.2 is an enlarged fragmentary side elevation showing one of the ournal boxes. Flg. 3 is an enlarged frag- I mentary plan view showing one of the j ournal boxes and adjacent parts. The frame is shown in section along the line 3-3 of Fig. 2. Fig. 4 is a fragmentary vertical viewof one of the boxes and adjacent parts, the frame being indicated in section. Fig. 5 is an enlarged fragmentary sectional view along the line 55 of Fig. 2.

Referring to the drawing, 1 represents as a whole a locomotiveframe which comprises side sections 2, 2 suitably connected together at their ends. Each of the side sections 2, 2 is formed of a single metal plate and is preferably reinforced along its upper edge by an angle bar. The side sectionsof the frame are provided with openings 3, 3 for with wells which receive the lower ends of i the springs, and secured to the frame at the upper part of the opening are seats 12, 12' which engage the upper ends of the springs. Each box is provided at each side with two similar flanges 13, 13 which embrace the adjacent parts of the frame plate. The flanges are provided with inclined inward extending lips let, 14: having arcuate inner edges. These lips engage the frame and prevent longitudinal movement of the box, but, at the same time, permit a limited rocking movement of the box with respect to the frame when the opposite ends of the axle move through different distances upward or downward. As has been stated, the lipsl l, 1&1 are inclined, the angle of inclination be ing the same as that of the side walls of the openings in the frame. The said inclined lips are sopositioned that their inner edges will lie outside of the edges of the opening in the frame when the journal box is its normal position. The wall of the journal box between the two flanges 13, 13 is vertical and it will be seen that between this vertitime, very flexible.

cal wall and the adjacent edge of the opening in the frame there is formed an upward tapering space 15.

Extending horizontally across the lower part of each axle opening and bolted at its ends to the frame is a connecting strap 16. Riveted to this strap 16 is a horizontal bar 17 located in the opening vertically below the journal box. This bar 17 is provided near its ends with two vertical slots 18, 18 which are directly below the before men- .tioned spaces 15 at the sides of the journal boxes between the boxes and the opening walls. Positioned within the tapering spaces 15 are correspondingly tapered gibs or wedges 19, 19. Each of these gibs or wedges can be adjusted vertically by means of a bolt :20 which is threaded at its upper end into an aperture in the gib and at its lower end extends through the corresponding slot 18 in the bar 17. A nut 21 locked in place on the bolt holds it against vertical movement. Preferably a lock nut 22 is provided for holding the bolt against turning after adjustment. Each gib preferably has formed in its inclined wall a groove adapted to engage the inclined surface of the frame.

It will be clear from the foregoing description that by turning the bolts 20, the gibs 19 can be moved upward or downward, and because of their engagement with the walls of the opening in the frame, can be adjusted to properly support and guide the journal box vertically. And it will also be clear that by moving one gib up and the other down, the journal box can be adjusted longitudinally of the locomotive without being displaced vertically.

23 and 24: represent wearing collars which are preferably formed of manganese steel.

Two of these collars are provided at each journal box, one of the collars having integrally formed pins 25 which fit into recesses in the box and prevent the collar from turning. The other collar has integrally formed pins 26 which fit into suitable apertures in the hub of the wheel to cause the collar to turn with the wheel. It will be clear that these two collars by engaging each other will take all of the wear resulting from thrust of the wheel and axle against the journal box.

It will be noted that by my invention I have provided a box which can engage with the side sections of a steel frame directly and without the use of any intermediate pedestal. The connection between the box and the frame is simple but, at the same Free movement of the box with respect to the frame either vertically or .angularly is permitted, and by means of the gibs, wear can be quickly taken up or the boxes can be adjusted longitudinally of the locomotive. The collars 23 and 24 can be readily removed and replaced and prevent all wear on the journal boxes and on the wheel hubs.

hat I claim is:

1. The combination with a locomotive side frame consisting of. a metallic slab of uniform thickness and provided with an opening having upright edges, of an axle box positioned within the opening and adapted to move vertically with respect to the frame, an axle journaled in the box, guides on the box for engaging the outer and inner surfaces of the frame to prevent movement of the box with respect to the frame longitudinally of the axle, wedges between the said guides on opposite sides of the box, each being between one edge of the box and the adjacent edge of the frame at the opening and means for adjusting the wedges independently of each other and holding them in adjusted positions.

2.
